COMBINATION LOCK.

Application filed July 9, 1923.

`provide a padlock of this character which may be readily and easilyoperated by persons familiar with the combination, but one which willnot yield under ordinary conditions when operated by unauthorizedpersons.

Another object of the invention is to provide a permutation lock whereinit will be impossible to remove the saine by disassembling the elementsthereof.

A still further object of the invention is the provision of a novel formof shackle wherein the shackle together with its supn port may be movedlongitudinally of the body of the lock in order to release the same.

l/Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Figure 9 is a sectional view taken on line 9 9 0f Figure 2.

Referring to the drawing in detail, the body portion of the lockincludes members 5 and 6 respectively, the members 5 and 6 beingpreferably circular in formation. Member is provided with an extension 7formed with external threads 8 disposed adjacent to one end thereof,which threads accommodate the internal threads of the member 6, tosecure the members 5 and 6 together.

Formed in the member 5 is an opening eX- tending throughout the lengththereof, which opening accommodates the plug or shackle support 9 formedwith a cut out portion 10 adjacent to one end thereof, to receive themovable locking dog 11. This locking dog 11 is formed with a pluralityof teeth 12, each of which having an inclined edge and a relativelystraight edge, the relatively straight edges being indicated at 13. Thestraight edges present shoulders to contact withthe tumblers and preventmovenient of the plugl or shackle support 9. when the shackle is in itslocked position. It will also be noted that due to this construction theshackle support may be inserted in the body 5, the locking dog 11 movinginto the cut out portion 10 as the teeth move past the tumblers. Asshown, the locking dog 11 is of a width less than the depth of the cutout portion 10 to permit the locking dog to move to a position where theends of the teeth 12 will lie below the upper edge of the shacklesupport 9 when the plug or shackle support 9 is to be removed.

The construction of the members 5 and 6 is such as to provide a spacebetween the adjacent. edges thereof, which space accominodates thetumblers 14, and while only two tumblers and locking disks have beenillustrated and described in this specication, it is to be understoodthat the number of tumblers and locking disks may be varied according tothe size of the lock.

The tumblers 14: are of the rotatable type and provided with graduationson their peripheries the inner edges of the tumblers being cut away toprovide notches 15 that receive the tongues 16 of the locking disks 17,thereby presenting a structure wherein the locking disks will tit withinthe tumblers to change the combination by moving the locking disks withrespectto ytheirtumblers, thereby moving the notches 18 ofthe lockingdisks with respect to the tumblers and graduations ontheperipheries.,thereof.

Associated with each tumbler is a stationary spacing disk indicated at19,which disks have inwardly extending tongues 20 adapted to move in thegrooves 21er the shackle supporting member 9 tor hold the spacing disksagainst rotary movement. A notch portion 22 is formed ineach spacingdisk 19, whichnotches are adapted toaline with the notches 18 of thelocking disk to all-dw the locking dog andthe shackle supporting`merrber' 9 to move longitudinally through the body portion of the lock.

Relatively thin spacing disks 23 hold the tumblers in 1spaced relationwith eachother, the spacing disks 23 being provided with notches topermit'the dog 1l to pass therethrough. Tongues`2t areprovided on thespacing disks 23 and extend laterally to contact with the lugs 25 of thetumblers so thatthe tumblers may be operated in an anti-clockwisedirection to indicate the starting point when operating'the lock in thedark. Inorder that the locking dog l1 will be normally urged to thelimit `of its outward movement, aspring mem-ber 26 is disposed betweenone wall of the cut out portion l0 and lower edge or' the dog ll.

Formed in the member' 6 is a groove 27 that accommodates the locking dogll, and

since the member 6 is threaded on the member 5, it is obvious that thelocking dog contacting with one of the side walls or' the groove 27 willprevent disconnecting the members 5 and 6 unless the locking dog 11 has`been moved within the contines of the cut out portion l0. Screws 28 passthrough threadedy openings in the member 6 and have their inner endspositioned in the openings 2 9 of the member thereby .insuring thealigning of the notches and grooves of the member 6 and tumblers, whenthe elementsy of the lock are assembled.

The lpivoted shackle is indicated at 3() and liason'e en d thereofconnected to the shackle support 9 at 31, lthe opposite end of theshacklebeing relatively straight at 32 toniove within the cutout portion33 ofthe shackle support 9 tol lock the shackle against movement. Tofacilitate the operation oi the lock in theY dark, each spacingdisk 19is supplied with a spring arm 34k that carries a pin 35 vextendingthrough a suitable opening therein, the pins having their outer endscurved andextended beyond the periphery of the locking disk associatedtherewith` so that as the tumblers operating thereover, are moved, thelingers 36 formed between the notches 15 will engage the pin 35 andrestrict movement of the tumblers to a degree, whereby the operator maybe notilied at each movement of the tumbler.

A handle 3,7; isdormed integral with the member 6 and affords means forthe operator to grip and hold the box stationary while the tumblers arebeing operated. From the foregoing-it will be obvious that when it isdesired to operate` the lock, the tumblers are moved to their proper4positions to cause thelnotches` of the locking disks connected thereto,to move into alignment providing a path for the locking dog llandpermitting the shackle `supportingl member 9 to move to a positionasindicated in dotted lines in Figure 3 or' the drawings, whereupon theshackle may be moved to its unlocked position.

What is claimed as new is 1. A permutation lock including a sectionalbody portion, one of said sections having a threaded extension, theopposite extension having threads to receive the threaded extension toconnect the sections, tumblers-and locking disks supported on thethreaded extension, a shackle support-ing member movable through the.body portion, locking dogs on the shackle supporting member and adaptedto cooperate with the locking disks to restrict movement of the shacklesupporting member, said locking disks having notches adapted to registerto allow the locking dogs to move therethrough, and a pivoted shackle onthe shackle supporting member.

2. A permutation lock including a sectional body4 portion, one of Saidsections having an extension formed with threads, the opposite sectionhaving a threaded opening to receive the threads ot the extension, thesection having the threaded opening iaving a groove 'formed in the wallthereof,

a shackle supporting member adapted to move longitudinally of the bodyportion, a locking dog carried by the shackle supporting member andadapted to move in 'the groove of the section ci the body having-thethreaded opening to restrict rot-ary movement of the sections withrespect to each other, tumblers mounted between the sections, lockingdisks controlled by the tumblers, said locking disks adapted to cooper`ate with the locking dog to restrict movement of the shackle supportingmember-with respect to the body portion. v

In testimony that I claim the foregoing as my own, I have hereto aillxedmy signature inthe presence oftwo witnesses.
